In Fig. lofvthe drawings; lrshow in front elevation a closetbowl l0 connected toa soil pipe `l2,`the end 12 of the soil pipe comprisinga pre-assembled part of my fitting, and this end 4maybe an elbow or a straight eX- tensionof the soil pipe line and connected atl its lower end (not shown) to the soil' pipe line v inthe usual manner. The" upper end' of the y `.fitting memberl l2 isformed to, have an in- Y ternal thread linut therein, of a substantial j length Yto receive an eXternally threaded cylindrical portion. 15V of a flanged closet bowl horn connecting member; generally indicated atvlin Fig. 2. The` member 16 is provided withV an annulariange l8witli-suitable arcuate slots 19 formed therein for the reception of bolts 20 which extend upwardly therethrough to engage the horn a of the closet bowl 10 by passing through apertures 10b formed in the horn. VThe length of the cylindrical portion 15 of the flanged member 16 p along J ring 28.

30 and the upper side of the locking` ring 26v may also be formed each with a substantial i ma lenjgth of the threaded portion 14 of the spoil pipe fitting member 12, whereby the flanged member 16 is vertically adjustable relative to the fitting 12 a considerable"distance (about 2 inches), readily destructible thread shielding member 22, which may be disposed between the under@ side of the flange 18 of the member 16 and the upper end ternal threads formed on the member 16 during shipping, and also to prevent cement or concrete comprising the floorV structure from flowing into contact with the 'threads fig. 2, this threadl As shown-in serves as an annular thereof. shielding member 22 mold member to form a justinent of the flange member 16,l relative to the'floor surface and the soil pipe fitting'12,

the thread-shielding member 22 being pref'- erably formed of corrugated paper, whereby lany surplus extension thereof above the floor be easily and quickly against the internal threads 14of the fitting 2, I provide an adf j ustable locking ring 26, beveled on its upper 12. As shown in Fig.

ide as'shown, and having notches 26a to facilitate its adjustment, which ring may support a packing means, such `as graphite threaded fibre 28 in annular form, and I in- `terpose a sealing disk 30 between the inner end of theflange fitting 16 and the packing ring 28 whereby the flange fitting 16 may be screwed down to cause the sealing disk 30 to be pressed into yair tight seal with the packing rllhe under side of .the sealing disk bevel surface to engage the packing ring 28, whereby said packing ring may be expanded and packed against the internal threads 14 of the fitting 12. The arrangement of bevel surfaces for packing the sealing means against theinternal threads 14 of the fitting 12 may be modified, as for instance, itis not essential to form a bevel surface on the inner l be of such extent in relation to theand I provide a cylindrical,

of the fitting 12 to protect the ezr-` recess in the floor structure, vthus permitting ready vertical adend 16a ortlie fitting 16 and also on the up-v per side of the adjustable locking ring 26. VIf preferred, either one of these surfaces may be substantially'flat provided the other one of these surfaces is bevelled. Similarly the sealing disk 30 need not be bevelled if the lockingring 26 is bevelled. e

rthis seaiing is shown asl being circular in cross-section for convenience, but when subv-v jected to pressure it takestlie bevelled form `of trie 'compressing surfaces of the disk 8 and the locking ring 26 and subsequently convtermin@ to the bevelled ends of the fitting 16 and locking Vring26,after the soil pipe line has been tested and the disk 8O removed. rIlhe removal of thefdisk 30 is Aaccomplished byy first completely removingthe fitting 16 from engagement with the soilpipe fitting 12, and

the disk may ldien be'liftedout of the fitting.

. It will be noted that theenlarged inner end 15 of the fitting 16 and the cross section of the ring l26 may bey the same, whereby `during manufa-ct-ureythe ring may comprise part 'of the fitting 16 untilthreaded, and then severedAv therefrom by a cut-o. tool. Y ,Y

In Ifig. 3, I show the flanged member 16,

locking ring 26 and 4packing'ring`28 4in adjusted position'to bring the horn flange 10a ofthe closet bowl into juxtaposition to the door surface 25a: It will be notedin this figure that Iv provide a second packing ring- 34 between the bowl horn and vanannularly shaped groove edgeY of the flangefitting 16, thus affording an. accurate sealbetween the flange' fitting and the closet bowl, which seal is independent of the seal whichI provide between the soil V pipe line fitting 12 and the angerfitting 16.1 The advantages, adaptability and economy of' installation of this'arrangement will be 'quite obvious to those ,slkilled'in the art. 1 -v In Fig. 2a, itwill be noted h tt the fiange 18 of the fitting 16 is offset or eccentric tothe threaded body thereof, wherefore the position of-the bowl maybe altered in any lateral direction with reference tothe soil pipe. The

recesses 16?) for packing are concentricwitliV 16bformed around the inner I iio the flange, whereforeitlie-horn'of the bowl may be .evenly sealed bypacvking, such as 34,

previously described.,

i ,e y i i In Fig. 5 I show a modified mannerof sealing the combined fitting disclosed` iii Figf2,

all parts of the fitting remaining the saine,` with theeirception of the sealingdisk 30 and,

inlieuthereof, `I provide alcap ymember 40 which may besealed tothe flange member e 16V by boltsl 41 extending through openings 42 (see Fig.' 4) formed inthe ange 180i'.l the fitting `16,l the cap beingformed to ene gage the sealing ring '34,1V and thelocking ring 26v serving to compress ythe packing ring 28 against the innerend 15 Vof theV fittingrz16,

while at the same time the bevelled surface'orf l surfaces will expandV and compress the pack! ing ring 28 against the internaltlireadslpofi y in this construction the flange member 16 is LBO provided with an internal pipe thread 43 into which is screwed a sealing plug 4:4: which may be removed after the soil pipe line has been tested. y

The feature of having the flanged bowl engaging member threaded to engage complementary threads on a second fittingv member which comprises a Vvertical extension of the soil pipe line, whereby a locking and sealing means may be disposed entirely within the soil pipe line without'undue restriction ofthe drainage capacity thereof has a distinct ad- Y vantage over the generalpractice of securing the end of the soil pipe line to the flange member. Further, by reason of-this arrangement, the fitting may be equipped at the source of manufacture with a soil pipe line sealing means in a very simple, economical manner, without in any way increasing the installation cost of the fitting nor introducing any new problems of installation, while affording ready adjustability of the combined fitting to eXtreme variations in the roughed in plumbing and variation in floor level construction. rl"he above features are such that the linemay be readily sealed for testing, and thereafter all joints thereof readily sealed in a permanent manner to prevent escape of foul gases from the soil line.

I claim:

l. A plumbing fitting, for use in connecting a plumbing fixture to a pipe system,

. wherein it is desirable toy test the system before the xture is permanently attached, j

comprising a fixture-connecting nipple externally threaded to adapt it to be screwed into a pipe ksection of the system, an externally threaded stop ring screwed into the pipe section to provide a seat for a gasket and` adapted to temporarily receive a testing cap, a gasket placed upon the ring, said ringand fixture nipple being so constructed and arranged that after the removal of the testing cap, the nipple can be adjusted to accommodate variations in floor thicknesses and said ring can be positioned to firmly clamp the gasket against the end of the nipple when y the nipple is thus adjusted. Y

2. A plumbing fitting, for use in connecting a plumbing fixture to a pipe system, wherein it is desirable to test the system before the fixture is permanently attached, comprising a flanged fixture-connecting nipple externally threaded to adapt it to be adjustably connected to the fioor terminus of a pipe section of the system, an externally threaded stop ring f screwed into the pipe end, to provide a seat for a gasket and a closure-testing cap, a gasket placed on the ring and clamped between the ring and the inner end of the fixturenipple, said ring and fixture nipple being so constructed and arranged that after removal ofi-[101,1

the closure-testing lcap the nipple and the gasket can be adjusted to accommodate variations in Hoor thicknesses and variations in the distance between the end of the said pipe section and'floor surface, and said ring being 35i positioned to firmly clamp the gasket against the end of the nippleV and against the internal threads of the pipe section when the flange of the nippleis disposed in Contactv with the fioor surface.

In testimony whereof, I hereunto affix my signature.
